For the umpteenth time (as long time CA readers will know) the blog is under heavy assault from people whose only wish is to read the latest from Steve McIntyre unfiltered. As a consequence, the MySQL db has caused lots of timeouts as the number of readers hits the maximum number of connections (which were […]
A reader just sent me the MBH reply, which is amusing. It’s late more on this tomorrow. MM comment and MBH reply
One of my brothers forwarded this to me with the caption: “Isn’t it comforting to know that when you are about to become a bear’s breakfast, your buddy is standing there taking photos?”
ABSTRACT: A new method is proposed for exploring the amplification of the atmosphere with respect to the surface. The method, which I call “temporal evolution”, is shown to reveal the change in amplification with time. In addition, the method shows which of the atmospheric datasets are similar and which are dissimilar. The method is used […]
One of the ongoing Team mantras has been that the Mann hockey stick has been supported by a “dozen independent studies”. Obviously, I’ve disputed the claim that these studies are “independent” in any non-cargo cult use of the term “independent”. A new article by Jones and multiple coauthors (Holocene 2009) comments on this issue.
A blog article here reviews the “standing joke” of Mann’s stubbornness in refusing to correct the wrong locations of MBH98 in the recent Mann et al 2007 network, where, as I observed, the prior errors are perpetuated without apology, even though the incorrectness of the locations has long been known to Mann. In a routine […]
Earlier today, I reported that I had been unable to access their server using R even to get a tiny data set. (I haven’t been working on NASA GISS data and haven’t downloaded anything much from them for months.) The following simple script failed for me (and for Roman in New Brunswick, Canada), but, strangely […]
This is a very pretty example, though the problem is endemic as Mann et al 2008 uses Mannomatic methods for industrial strength voodoo correlations. This one came up from trying to replicate Mannian confidence intervals from original data – an effort which promptly foundered because my CPS emulation, which, after much effort, finally worked on […]
Anthony has a post reporting NOAA’s 2008 results, with NOAA reporting: For 2008, the average temperature of 53.0 degrees F was 0.2 degree above the 20th Century average. Anthony showed the following image from NOAA: Readers need to keep in mind that there is a substantial “divergence” between NOAA US and NASA US temperatures as […]
Ex post selection based on correlation has been a long-standing issue at this blog (and has been independently discussed at other blogs from time to time – Luboš, Jeff Id and David Stockwell have all written on it independently. The issue came back into focus with Mann 2008, in which there is industrial strength correlation […]
